Breeding for resistance to TB and liver fluke can help protect your herd from TB and liver fluke infection.
Each animal's breeding value is expressed as the predicted prevalence of TB or liver fluke in that animal's progeny.
Therefore, lower breeding values are more desirable.
Breeding values for resistance to TB and liver fluke are not yet incorporated into the EBI, or Eurostar Indexes.
Therefore, the optimum breeding strategy is to select bulls for mating that have the highest overall index with the
lowest expected prevalence of TB and liver fluke.
For 2019, breeding values for resistance to TB and liver fluke are only available for AI bulls that are either genotyped
or have at least 20 progeny records. Breeding values and further information can be found here.
